Non-Isothermal Polymerization of Styrene

Abstract

<p>The non-isothermal polymerization of styrene under runaway chemically initiated reactions was studied. A system of multiple initiators was used. The experiments were performed in an insulated batch reactor. Experimental temperature and pressure profiles with respect to time were obtained and used to evaluate a mathematical model at high temperatures. Molecular weights and conversion measured by gel-permeation chromatography (GPC) provided further evidence about the adequacy of the model. The behaviour of a non-isothermal polymerization if fully discussed, including such phenomena as depropagation, gel-effect and dead-end polymerization.</p>
